14 Claims.

This invention relatesl to sliders such as used on separable fastener stringers of the double action type, providing two way mounting and operation of sliders along the stringers. More particularly, the invention deals with means for coupling and permanently locking, through the medium of a padlock or similar means, two sliders against relative movement with respect to each other, so as to maintain a fastener closed, regardless of the position of the tandem or coupled sliders on the stringers. Still more particularly, the invention deals with a slider construction of the kind defined wherein each slider is of the same construction so that two similar sliders mounted in reverse directions on the stringers may be brought into intercoupled relationship for the reception of a padlock or similar means for positively uniting the sliders against separation. The novel features of the invention will be best understood from the following description when taken together with the accompanying drawing, in which certain embodiments of the invention are disclosed, and in which the separate parts are designated by suitable reference characters in each of the views; and in which:

Fig. 1 is a plan and sectional view of a pair of sliders made according to my invention, showing the same in coupled relationship and indicating part of the locking bolt of a padlock therein; and

Fig. 2 is a side view of the structure as seen in Fig. 1, with parts of the construction broken away and in section and indicating parts of pulls employed on each slider.

The sliders herein shown and described are adaptable for use on stringers of the type and kind disclosed, for example, in my prior application, issued as Patent Number 2,331,618 granted October 12, 1943, which adapts sliders for movement along the stringers with the sliders in any position thereon, thus permitting an arrangement of two similar sliders IU-lll' on stringers with their narrow ends I I-I I' disposed in opposite directions to each other and their flared diverging channelled ends |2--I2' disposed adjacent each other. The sliders have top walls l3-I3' having inturned iianges M-M' at their outer edges. The sliders also include. the similar bottom walls l5-I5' joined with the top walls by connecting webs or frogs IB--l6', these frogs forming the usual diverging channels well known to devices of this kind.

Arranged on the top Walls I3--l3', adjacentthe ends H-I I' are upstanding bearings Il--l 1 ln which are mounted pin portions I8-l8 of lock 2 and riveted over ends engaging washers 20--20 to support the levers IB--IB' firmly in the bearings.

The levers |9-I 9 have inwardly offset end p0rtions 2|-2I which extend beyond the limits of the ends I2--I2' and are adapted to overlap in the manner clearly illustrated in Fig. 1 of the drawing. These ends 22--22' therein adapted to receive the U--bolt or element 23 of a padlock 24, as clearly illustrated in Fig. 2 of the drawing, part of the bolt being shown also in Fig. 1.

The apertures 22--22 extend into elongated apertures 25--25' arranged along the levers |9-I9 to a point adjacent the pin ends thereof and in these apertures, suitable pulls or lingerpieces '2B-26' are adapted to be arranged for independent operation of each of the sliders when uncoupled.

4 The top walls of the sliders also have upwardly and outwardly extending plates or walls 21--21 so offset that their adjacent surfaces are brought into close proximity to each other, as clearly seen in Fig. 1, and these plates have apertures 28-28 therein registering with the apertures 22--22' also to receive the bolt 23. This construction keeps the arms I9--I 9' down upon the upper wall portions I3-l 3', as will be apparent.

The upper walls I3--I3' have elongated openings 29-25' formed therein to receive downwardly extending lock elements or ngers 30--30' on the levers I9-I9. These elements extend into the channels of the slider to engage the scoops on the stringers and will serve to permanently lock the sliders in any desired position on the stringers. It will be understood, however, that in some forms of construction, these lock pins are not absolutely essential, as the mere locking together of the two sliders retains the fastener against opening. These lock elements are only desirable when it is important to retain the lock elements in a definite position on the stringers, otherwise, the coupled sliders could be moved anywhere along the stringers.

Adjacent the apertures 29-29, the upper walls l3-l3' are provided with upstanding lugs 3 |-3 l which are arranged adjacent the levers ils-I9' andserve to reinforce and strengthen the coupling engagement of the sliders and to maintain the levers within and between the wall portions defined by the members 2l-3I and 2'|-3I'.

Upon removal of the padlock or other locking member employed to retain the sliders in locked engagement, the 'levers I9-I9 may be swung on the pivots I8--l8' to disengage the lock pins` have large apertures 30-30' from the stringers and permit free independent movement of the sliders along the stringers, as with other devices of this kind. Where the question of strength and maintenance of the sliders in close proximity to each other is not of too great importance, the walls or plates 21-21' can be disposed with, and the bolt 23 of the padlock simply passed through the apertures 22-22' of the levers. It will be apparent that the coupling engagement of these levers will limit relative swinging movement thereof outwardly with respect to the upper walls of the slider.

By using sliders of identical construction, no lefts and rights are required. In other words, a single slider is produced. In this manner, all problems from a standpoint of manufacture are dispensed with and this is also true with respect to the levers employed on each of the sliders.

It will be apparent that the sliders when brought into coupled relationship, have the apertures of the plates and levers in registering alinement with the axis of said apertures on abutting or adjacent ends of the sliders. In other words, the axis of the apertures in the plates 21-21' is disposed at, or slightly beyond the end of the slider or the web or frog portions |8-I6' thereof.
